Package: effect
Module: Trie

Trie.map

Maps over the entries of the Trie using the specified function.

Example

import * as assert from "node:assert"
import { Trie, Equal } from "effect"

const trie = Trie.empty<number>().pipe(
  Trie.insert("shells", 0),
  Trie.insert("sells", 1),
  Trie.insert("she", 2)
)

const trieMapV = Trie.empty<number>().pipe(
  Trie.insert("shells", 1),
  Trie.insert("sells", 2),
  Trie.insert("she", 3)
)

const trieMapK = Trie.empty<number>().pipe(
  Trie.insert("shells", 6),
  Trie.insert("sells", 5),
  Trie.insert("she", 3)
)

assert.equal(Equal.equals(Trie.map(trie, (v) => v + 1), trieMapV), true)
assert.equal(Equal.equals(Trie.map(trie, (_, k) => k.length), trieMapK), true)

Signature

declare const map: { <A, V>(f: (value: V, key: string) => A): (self: Trie<V>) => Trie<A>; <V, A>(self: Trie<V>, f: (value: V, key: string) => A): Trie<A>; }
